SPECIFICATION forming part of Letters latent No. 648,372, dated May 1, 1900. Application filed July 12, 1895. send No. 555,733. (No model.)

ful improvements in presses for baling cotton.

into cylindrical bales; and the object of my invention is to provide and produce a press for this purpose which will be simple in construction and effectivein use and wherein bales of the most desirable form may be produced. i I

The type of cotton-press to which myinvention relates is that which was. invented by John W. Graves and on which several Letters.

Patent of the United States have been granted,

said patents being numbered 510,385 510,386,

510,387, and 510,388, an bearing date the 5th day of December, 1893. In the Graves press an endless belt, was employed which" was mounted on rollers and in which aloop or bight was formed which passed around a core, means being provided for applying tension to said belt, whereby the enlargement of said loop or bight would be retarded. In the operation of the Graves press'the cotton was first formed into a continuous sheet or bat by an ordinary condenser,which sheet orjbat was fed to the press Within said loop or bight. Power was then applied to the belt, so as to drive it continuously, thereby causingithe sheet or bat to be wound spirallyonthe core,

the bale being partially encircled at all times by said loop or bight. By means of the tension device which was applied tothe-belt,- whereby the tendency of the loop or bight to enlarge was retarded, pressure was applied to the bale during its formation, so that when sufficient cotton had accumulated around the core a very dense cylindrical package was produced, after which and preferably While the bale was still in the press it was covered in any suitable way and then removed. While the employment of an endless compressionbelt as described for the first time by said Graves was very desirable in cotton-presses, as by its use a large proportion of the surface of the bale was subjected to pressure, particularly near the close of the baling operation, yet the use of such a belt in the way described by Graves was open to objection in practical use for the reason that as the bale enlarged the surface compressed by the belt correspondingly increased, and it became necessary, therefore, to also increase the tension of the belt, so that the pressure per square inch on the bale would remain practically constant. Therefore when a belt made of material such as leather was used it was liable to become broken under the extreme pressure applied thereto, or when made of :metal links the belt became very quickly worn out under such pressure.

. In my improved press I still retain the endless compression-belt first described by Graves and use it to partially encircle the bale throughoutits entire formation; but instead of applying pressure to the bale by a ,tension device operating directly upon the belt I employ baling-rolls for effecting the compression of the cotton, the belt being used principally to prevent the bale from expanding out of shape under the compressing efiect-s of the rolls, whereby bales of comparativelylarge diameters maybe produced. In this way I retain all the advantage incident to the employment of an endless compression-belt, and by removing all excessive strains there on I prevent the belt from becoming worn out or broken in ordinary use.

Broadly considered, therefore, my improved cotton-press consists in. the combination of an endless belt in which a loop or bight is formed which partially encircles the bale throughout its entire formation and two or more baling-rolls operating in conjunction with said belt for effecting the compression of the sheet or bat of cotton as it is wound in place on the bale.

My present invention also has reference to improved mechanism for withdrawing the stru'ction, all as will be more fully hereinafter whereby a very thick bat or sheet maybe obtained from an ordinary condenser without the necessity of reducing the peripheral speed of? the condensing-cylinder thereof {also} to.

an improved device Wherebywhen the bale is being covered in the press the cotton coming from the condenser may be deflected out of its normal course and be accumulated on a" separate roll, so that the gin and condenser may work continuously; also, to improved mechanism for applyingpressure to the compression-rolls, and to further details of condescribed and claimed.

The amount of pressure imposed, by said .buffers may be regulated "by-adjusting-screws128. Said buffers may, however,- be dispensed with, and an inelastic pressure may be imposed between the rolls 22 and 26 by the adjusting-screws 28.

. ':29 is an auxiliary supporting-frame bolted toeach side frame 2.; 30 is a gear-wheel which meshes with the gear-wheel 20 and which is keyed to a shaft 31, mounted in said auxiliary frame, saidshaft 31 having keyed to it a roller 32, Fig.4, made either of metal or of fwood, preferablythe former. gins from the blast by' which i sa is agear-wheel. which is keyed on the on a shaft 34.

40 is a swinging arm mounted at its upper end at each side of the machine in the auxiliary supporting-frame 29, each arm being provided with an open bearing 41 at its lower end.

42 is a small accumulating-roll carried in the open bearings 41 and which is made, preferably, of wood or metal, being armed with small projecting teeth or pins for picking up the bat or sheet when necessary. This accumulating-roll 42 may be brought down into contact with'the roller 17; but it is normally elevated up and away from said roller, so as not to interfere with the cotton passing over the same.

43 is an endless compression-belt made,preferably, of steel links, as I will presently explain, and which passes over and around a series of sprocket-wheels keyed to the main shaft 13, thence around the core 45 to form anencircling loop or bight 46, thence over the roller 47, mounted in bearing-boxes 48 in the upper ends of the swinging arms 49, to be presently described, thence around one of the baling-rolls 50, thence down and around an idler 51, and thence over the other balingroll 52.

The swinging arms 49 are each of the general shape shown, being hinged to the front of each side frame 2 by a heavy joint 53, whereby said arms, when desired, may be swung downward, so as to open the loop or bight 46 for the removal of the completed bale.

54 is a roller mounted in rigid bearings in the side frames 2 at such a position as to be borne upon by the bight or loop 46 when the bale has reached its maximum diameter and which serves to then commence to compress the bale as cotton accumulates thereon. Said swinging arms are to be counterbalanced in any suitable way, so that they will immediately and automatically return to their proper positions after the bale has rolled out of the machine.

56 is a lug or ear cast on the upper face of each swinging arm 49, and 57; Fig. 4, is a horizontal bar or rod which engages in front of said ears when the swinging arms 49 are tov be locked in place. Said rod or bar 57 is mounted in bearings 58, carried in swinging arms 59, which are hinged to the side frames 2 of the machine. Asmall handle (not shown) may be attached to one end of the bar or rod 57, whereby the said rod or bar may be rolled on the lugs or ears 56, so as to unlock the upper end of the swinging arms 49 when it is desired to remove the bale from the machine. The rear face of each lug or ear 56 is inclined at 61, as shown, Fig. 4, whereby when the 63 is a slotted bearing formed in each swinging arm 49 in line with the core 45, and 64 is a sliding bearing-box in each slotted bearing 63 and carrying the shaft of the balingroll 50.

65 is a slotted bearing formed in each side frame 2 in line with the slotted bearing 63, and 66 is a bearing-box working in each of said slotted bearings 65, said bearing-boxes 66 carrying the shaft .of the other balingroll 52.

67 is a heavy bearing formed on each side frame .2, (see particularly Fig. 5,) each of which bearings 67 supports one of the end flanges 68 for the bale. Each end flange 68 (see Fig. 5) is of the general form shown, being provided with an integral sleeve 69, which works within the bearing 67. Each end flange is made, preferably, of cast metal, perfectly plain onthe inner side, which comes in contact with the bale, and gradually tapered on its outside toward its periphery, there being a flat portion 70, provided on the outside of each end flange, which works against the inside of the corresponding bearings 67. Ordinarily when the bale is being formed the end flanges are held a short distance inward from said bearings 67, so that when the core is released the said end flanges may be separated slightly under the expansion of the cotton, whereby the bale may be more easily removed from the machine.

The core 45, as shown particularly in Figs. 5 and 9, consists of a single polished-steel shaft about two inches in diameter and provided at one end with a collar 71, which fits within a recess 72, Fig. 5, in the cylindrical sleeve 69 of one of the flanges 68. The other end of the core 45 is provided with .an inclined keyway 73 therein, in which a tapered key 74 is inserted. This key 74 fits against the cylindrical sleeve 69 of the other end flange. The key 74, as shown, is provided with a flat portion 75, by which it may be driven in place, and with an integral curved finger 76, extending past the end of the core and by means of which the key may be driven out when desired. The end of the finger 76 being in line with the center of the core travels very slowly, and may be easily hit with'a hammer for driving out the key. Instead of employing a key 74, as explained, for this purpose the end of the core may be secured in place in any suitable way, such as by a nut engaging with threads on the outside of the end of the core or by a screw-bolt engaging with a screw-threaded chamber formed in the end of the core.

4 g ams-2' 77 is -a core-rack for withdrawing the core shaft turned down on one side and'having teeth 78 cut therein. The head of the corerack is provided with a vertical passage 79 independent of the latter.

therein and with a horizontal passage 80, Fig.

9, leading into the same.

81 is a short cylindrical steel rod rigidly secured in the end of thecore adjacent to the "collar 71am inserted in the passageBO, be-

ing provided with a nut or collar 82 at its outer end, which nut may be secured'in position through the passage 79. 'By means of this construction it willbe observed thatI provide a swivel connection between the core and core-rack, so that the core may revolve Referring to Figs. 5 and 6, 83 is a web-cast- Thisca'sting consists of aplate 84,having stiffening-webs machine directly above and to one side'of the bearing 67. The web-plate 84 is arranged at an angle with respect to the plane of the ma- 85' and 86 at its top and bottom andwith a base-plate-87, which is bolted to a suitable bed cast with one of the side frames 2 of the chine, as shown.

.88 is a bearing formed on the lower part of theframe 83in. line with the bearing 67, andin whichbearing 83 is mounted'the end of the core-rack 77. The bearing 88 is open at its end, whereby said core-rack may he moved withdrawn.

out through thesame when'the core is to be 89 89 are bearingsin line with each other formed on' the end of the supporting-frame 83 and in which a shaft 90 is mounted, said shaft carrying a spur-wheel 91 at its lower end,

-which meshes with the teeth 78 of the corerack7-7. q

92 is a worm-wheel turning loosely upon the shaft 90 nearits upper end above the top bearing 89. 93 is a clutch for throwing said worm-wheel into connection with said shaft 90 when thecore is to be withdrawn. This clutch 93 is ope-rated by a lever 94, mounted on a bracket 95, secured to or cast integral with the supporting-frame 83.

-. 96 is a bearingformed at the upper part of the supporting-frame 83 at one side thereof {in line with the main shaft 13, and said main shaft extends through said bearing 96an'd is pulley 100, mounted in a casting 101, secured to the side frame 2 or to the supporting-plate 87. This cable 99 is provided at its lower end with a weight 102, which hangs below the mgchine. r

103 is a wheel keyed to the lower end of the shaft and provided with radial handles 104, by which it may be easily turned when desired. I 1

105 is a collar surrounding each end. of the shaft of the baling-roll 50 or a cylindrical projection on each bearing-box 6 4, as maybe desired. 106 is a corresponding collar at each end of the shaft of the baling-roll 52;

' 107 is an integral rod for each collar 105, and 108 is a corresponding rod for each of the collars 106. The ends of the rods 107'and .108 are connected by a short heavy chain or links 109.; r i

110 is an ordinary turnbuckle for taking up any slack in the parts or for adjusting the parts.

111 is a rack at each side of the machine, 'providedwith' a roller 112 at its upper end, which roller bears upon the chain or links 109. The teeth of each rack 111 engage with a pinion'113 at each side of the machine, said "pinions beingkeyed to a shaft 114, which is mounted in suitable bearings formed in the side frames 2. The said shaft carries a facewheel 115, which is located at one side of the machine. l

116 is a steel band or strap faced with leather or some other appropriate material, which is anchored to a heavy pin 117 in a plate 118, bolted to one of the skids 1, upon which the machine is supported. The other end of this steel strap is connected to the free end of a short lever-arm 119, which is arranged in an inclined plane, as shown with respect to the bed-plate of the machine, and which is provided with a longer horizontal lever-arm 120. These arms 119 and 120 are mounted in the plate 118.

121 is a weight which is applied to the lever-arm 120, being movablethereon, and by which the friction between the leather surface of the steel band 116 and the face-wheel 115 can be suitably regulated. The racks 111 are kept in engagement with the pinions 113 by rollers placed behind said racks or in any suitable way.

The idler or guide-roller 51 ispreferably guided in its movements up and down by light guides 122 123, bolted to the bottom of the machine, and which are provided with vertical slots l24'therein, in which the bearing-boxes of the guide-roller 51 move. These guides 122 123 are connected together at the lower ends by a rod 125. I

The various rolls employed in the machine are preferably of the construction shown in Fig. 10, to which attention is-directed.

126 indicates the shaft of a roll which works in the proper bearing-boxes, and 127 is the roll. as shown. In large rolls one or more strengthening-ribs 12 8 may be formed-on theinside of the periphery.

129 :indicates collars cast with the roll and ,Wh'ih are fitted to the shaft 126. These collars are rigidly keyed to said shaft by means of set-screws 130, which may be introduced This roll is preferably cast hollow,

within which will engage the teeth of the Va-- rious sprocket-wheels for driving the belt, as I will presently explain. In order that the edges may be approximately straight, I employ single links 135 on the outside, the holes for the bearing-rods being flared slightly, whereby the said rods may be headed within said holes. I also provide an extension-piece 136, riveted to the outside of each of the links 132, which extension-pieces fit between thelinks 135 135. The faces of the links which press against the bale are preferably curved slightly, as shown, although this is not an essential.

The compression-belt 43 is of approximately the same width as the desired bale and works within and between the end flanges, being in contact with the core when the operation commences.

The construction of sprocketwheels for driving the compression-belt will be understood from an inspection of Figs. 11 and 12, to which attention is directed. The main shaft 13 between the side frames 2 2 is provided with a series of disks 137, keyed there-.

on, each disk being provided with sprocketteeth 138, preferably four, formed therewith, the sprocket-teeth of one disk alternating with the sprocket-teeth of the other disk, whereby a practically-continuous cylinder will be produced having teeth which engage with the openings formed between the links of the compression-belt. A disk 139 without teeth is secured to the shaft 13 at each side of the series of disks 137 and supports the links 135 and the extension-pieces 136 of the outside links 132 at the sides of the belt. In this way a very cheap and effective sprocketdriving mechanism will be produced, the disks 137 being easily removable when worn.

In the formation of cotton into cylindrical bales I have found from extensive experiments that it is necessary, or at least highly desirable, that the cotton should at all times be subjected to pressure as 'it is wound in place on the bale. I find, however, that during the preliminary stages of baling cotton care should be taken to prevent excessive pressure being applied thereto, for the reason that the cotton tends to become caked on the core and its quality and fiber are thereby seriously damaged.

In my improved press, aswill be seen from an inspection of the drawings and as I will presently explain, the cotton is subjected to two separate and distinct pressing operations,

Gil

the first press ur'e-name1y, that produced entirelyby the belt-being sufiicient to compress the cotton around the core and on the bale and expel therefrom most, if not all, of the air contained therein, and the second pressure produced by the baling-rolls being sufficient to act upon the outer layers of the bale and press them tightly in place, whereby the desired degree of density will be obtained. In this way I produce a bale which will be of great density throughout and wherein none of the cotton will have been subjected to such an excessive pressure as will in any way affect the quality of its fibers.

The operation of my improved press is as follows: The gins are operated in the usual way and blow the cotton in the form of flakes onto the gauze cylinder or cylinders of a suitable condenser, Fig. 13 showing a good type thereof and wherein the cotton is formed into a continuous sheet or bat. The pulley 9 being thrown into connection with the driving shaft 7, the pinion ll, meshing withthe gearwheel12, will operate the main shaft 13 of the machine. The various sprockets 137 137, which are keyed to this shaft, engaging with the belt 43 will operate the same continuously. The said belt will be at its lowest limit of movement, the loop or bight 46 thereof being in direct engagement with the core 45. The gear-wheels 14, 15, 19, 20, 30, 33, and 33 will be rotated, thereby operating the several rollers 17, 22, 26, 32, 35, 36, and 38, and the belts 37 and 39 in the direction of the arrows. Since the belts 37 and 39 are arranged to travel at a much slower speed than the sheet or bat coming from the condenser, the said sheet or bat asit enters the machine between said belts will tend to be lapped back and forth in the space between said belts and be passed out between the rollers 32 and 35 in a much thicker form than originally. By adj usting the relative speed of the condensingcylinder and said belts the desired thickness of the bat can be easily obtained, it being obvious that by employing a very thick bat the speed of the machine can be materially reduced and there will be muchless wear of the partsin consequence. It is to be understood, however, that the thickness of the bat should not be made so great that the proper density of the bale cannot be obtained. The thickened bat or sheet after leaving the lower ends of the belts, by which it will be slightly compressed, is passed between the heavy compression-rolls 22 and 26, by which it will be subjected to avery great pressure, such pressure being sufficient to expel all the air from the bat and togiveitstrength andimpart to ita blanket-like appearance, but not being sufficient to injure the fiber. The compressed sheet from these rolls passes over the roller 17 and thence between the roller 47 and the sprocket 137 into the loop or bight 46 of the compression-belt. The cotton on reaching the bottom of this loop or bight comes in contact with the core 45 and is wound around the coreconvolutional'ly by the action of the belt, the core revolving with-the bale. As the cotton accumulates around the core it tends to distend the loop or bight and slowly elevates the guide-roller 51. The baling-rolls 50 and 52 at this time will be in their inner positions, said baling-rolls working. between the end flanges 68,but out of contact with the loop or bight, During this preliminary compression the cotton will be subjected to the action of the belt alone, whereby the danger of caking thecotton on the core or of injuring its in engagement with the pinions 113, revolve thelatter. The pinions 113 in revolving carry theQfa'ce-Wheel 115 with them against the friction imposed by the leather innerface of the steel band 116, the amount of friction being regulated by the Weight 121 on the lever-arm "120'. The baling-rolls 50 and 52 will in this way tightly compress each layer of the sheet or bat as it is wound in place on the bale,

which pressure will be automatically in creased as the bale increases in size by reason of the increase in the angle between the arms 107 108 and the racks 111. When the bale has reached its maximum diameter, or, in other words, when it'is so expanded that the loop orbight 46 of the belt comes in contact with all the rollers that encircle it, the core is to be withdrawn. The pin 74 isfirst removed from the core, which will allow the end flanges I 68 to separate slightly, so as to allow the bale 'ment with the shaft 90.

to pass easily from between the same, and thehandle 94 is operated, so that the clutch 93 will throw the worm-wheel 92 into engage- This worm-wheel will then be turned by the worm 97, operated by the main shaft 13, and the shaft 90 will be operated, whereby. the pinion 91, engaging with the teeth 78 of the core-rack 77, will Withdraw the core from the bale. By providing a short space at the end of the teeth 78 the movement of the core-rack will be arrestweight of the bale, are moveddownward and allow the bale to roll out of the front of the ant. the accumulator-roller 42 is brought down machine, where it is'received by the attend- While the bale is being boundand tied,

into engagement withthe roller 17, and the cotton which passes over said latter roller will be picked up by the teeth of the'accumulatorroller and be wound up thereon. When a new bale has been started, the accumulatorroller 42, with its accumulated cotton, is removed from the open bearings 41, and its position is reversed, so that the cotton may unwind therefrom and enter the machine with the bat which comes directly from the condenser, or the cotton. on the accumulatorroller maybe unwound therefrom in any other suitable way. After the bale has left the machine the swinging arms 49 will be automatically returned to their positionby the counterbalancing-weight or other means and will be locked. Before this isd'one, however, the core should be replaced in the machine, and this is effected in connection with the expulsion of the'bale in the following way: Just as the bale commences to leave the machine the handles 104 are grasped by the operator, by which the shaft and spur-wheel 91 will be turned, and the end of the'core will beheld in engagement with the bale with considerablepressure; The operator maintains this pressure as the bale rolls out of the machine, theen'd of the core remaining in engagement with the bale, so that the end of' the core will pass between the bale and the belt, after which, by operating the hand-wheel 104, the core may be easily returned to its position and again held by means of the key74. These operations are materi ally facilitated'by employing a counterbalance-weight 102, which counterbalances the core and enables the operator to easily move the same. I

Many of the improvements which I have above described are specific in character and by means of which a very efficient and desirable cotton-press is produced; but other improvementsare of a generic character, and I desire to have.them construed herein in as broad a light as possible. For example, I believe I am the first person. to suggest a way by which the hat or sheet coming from the condenser can be effectively thickened, whereby the speed of the machine could be correspondinglyred'uced, so as to save wear. This improvement is of particular advantage, because that. a sheet or batof any desired thickness can be produced without altering the peripheral speed of the condensing-cylinder. It is obvious that instead of employing two belts,

IIO

such as I have described, two or more rollers press is the idea which I have described therein of employing a belt for effecting the preliminary compression of the bale and two or more baling-rolls for compressing the bale during its final stages. This idea is of particular importance, as I am thereby enabled to produce a bale which will be of great density and wherein the fibers will not he affected or damaged to any extent. By employing an endless belt in connection with baling-rolls I also prevent the bale from expanding on each side of the rolls, and I therefore produce cotton-bales with comparatively great diameters.

Another improvement on which I lay particular stress is the general means I have shown for withdrawing the core from the bale and for returning the core after the bale has been removed from the machine.

A still further improvement which is of great value is the use of the accumulator described for picking up a sheet or bat and accumulating the same during the covering and tying of the bale, as in this way I am enabled to operate the press while the gins are continuously working.
